Imaggeo on Mondays: Escullos

This picture shows a Quaternary aeolianite fossil dune at the Escullos beach, in the Nature Reserve of Cabo de Gata (Almeria, Spain). Originally a soft accumulation of sand grains, shaped by the wind into large mounds and ridges, the dunes eventually turn into rock. As the sediments compact under their own pressure and expel any …[Read More]

Imaggeo on Mondays: Retreating Glacier

The Svalbard archipelago is considered to be one of the best places to study the geological history of the Earth because its rocks represent every geological period. This image shows a view from the peak of Fugleberget (569 m a. s. l.; 77º 00’ N, 15º 30’ E) on the south-western coast of the island …[Read More]

Imaggeo on Mondays:  Pyroclastic flow, Montserrat

Below the warm and tranquil waters of the Caribbean, some 480 km away from Puerto Rico, the North America Plate is being subducted under the Caribbean Plate. This has led to the formation of the Lesser Antilles volcanic arc; the result of the formation of reservoirs of magma as fluids from the down going North …[Read More]

GeoEd: Education vs. Communication

GeoEd: Education vs. Communication

In this guest blog post, Sam Illingworth, discusses the perceived differences between science education and science communication in light of a recent publication on this very subject. If you are involved in either of these, we’d love to hear your opinions on how you think they differ (if at all) and how the approach to …[Read More]

Imaggeo on Mondays: An explosive cloud

One of the world’s most volcanically active regions is the Kamchatka Peninsula in eastern Russia. It is the subduction of the Pacific Plate under the Okhotsk microplate (belonging to the large North America Plate) which drives the volcanic and seismic hazard in this remote area. The surface expression of the subduction zone is the 2100 …[Read More]

Geosciences Column: The quest for life on Mars

Understanding where we come from and whether Earth is the only habitable planet in the Solar System has been a long standing conundrum in science. Partly because it is our nearest neighbour, partly because of its past and current similarities with our own home, Mars, the red planet, is a likely contender in the quest …[Read More]

Geosciences Column: Fire in ice – the history of boreal forest fires told by Greenland ice cores.

Burning of biomass contributes a significant amount of greenhouses gases to the atmosphere, which in turn influences regional air quality and global climate. Since the advent of humans, there has been a significant increase in the amount of biomass burning, particularly after the industrial revolution. What might not be immediately obvious is that, (naturally occurring) …[Read More]
